Study Guide for CS 303E Test 2 (Summer 2011) on 31 Jul 2013
* Loops
* Functions - user defined and built-in
* Math Functions
* Strings and String Functions
* Reading and Writing Text Files
* Lists and List Functions
* The questions will be similar to quiz questions and the
tutorial exercises that you have done on Coding Bat.
* Here are some additional String problems that you want to
consider. In all cases you will be asked to write a function.
- Write a function that accepts a String as input parameter
and returns True if it is palindromic and False otherwise
- Write a function that accepts two Strings as input parameters
and returns True if they are anagrams and False otherwise
- Write a function that accepts a String and a rotation parameter
and rotates the String by that amount and returns it. For example,
given a String "computer" and a rotation parameter of 2, it will
return "ercomput".
* Here are some file manipulation problems to look at.
- Write a function that accepts two Strings - the name of an input
file and a target String. It will return the number of occurences
of the target String in the file.
- Write a function that accepts the name of an input file and a list
of forbidden words. If any one of those forbidden words exists in the
file it will return False and True otherwise.
* Here are some list problems for you look at:
- Write a function that accepts a 1-D list as input parameter and
returns a 1-D list that is a copy of the input list where each
element of the input list is multiplied by the same factor.
- Write a function that accepts a 2-D list as input parameter and
returns a 2-D list that is a copy of the input list but each element
in the input list is incremented by the same number.
- Write a function that accepts a 2-D list as input parameter and
prints the sum of each row on separate lines
- Write a function that accepts a 2-D list as input parameter and
prints the sum of each column on separate lines
- Write a function that accepts a 2-D list as input parameter and
prints the sum of each diagonal. Assume that the 2-D list is square.
- Write a function that accepts an input parameter n (that is a
positive integer) and returns a 2-D list containing all the numbers
from 1 through n (inclusive), their squares, and their cubes. For
example if n was 5 your function will return the following 2-D list:
[[1, 1, 1], [2, 4, 8], [3, 9, 27], [4, 16, 64], [5, 25, 125]]
- Write a function that accepts a 1-D list of integers and returns
True if all the numbers are in ascending order and False otherwise.
(It will return True if all the elements are the same.)
- Write a function that accepts a 2-D list and returns a 2-D list
with all the rows reversed.
- Write a function that accepts a 2-D list and returns a 2-D list
with all the columns reversed.
- Write a function that accepts a 2-D list and returns a 2-D list
that is the transpose of the input list, i.e. the rows and the columns
have been switched.
